Minister of Regional Development and Infrastructure, Davit Shavliashvili, has submitted his resignation.

“The decision has been caused by deteriorating health of Davit Shavliashvili,” the ministry said in a brief statement posted on its website on April 21 without providing other details.

Shavliashvili, 31, who served as infrastructure minister since July, 2014, attended government session on April 20 and reported to PM Irakli Garibashvili about completion of construction of a new residence on Atoneli street in Tbilisi, which government wants to serve as new presidential palace.

Before becoming the minister, Shavliashvili was head of the department of roads at the same ministry since April, 2013 and before that he was head of the natural resources agency at the ministry of energy, where he was appointed in December, 2012.

Rumors about his possible resignation intensified in March, when one of his deputies, Nodar Javakhishvili, criticized Shavliashvili in a newspaper interview saying that he “can’t say he [Shavliashvili] is a good minister.” Javakhishvili, who was head of ex-PM Bidzina Ivanishvili’s bank, Cartu, was appointed as deputy minister of infrastructure and regional development in December, 2014.
